Existing secular social relations are just as oppressive as religious social relations. It is not enough to understand or interpret the world from an atheistic viewpoint. The stinking mess of capitalism needs to be changed, revolutionised.

IV Human essence
Combine 6, 7, 9 and 10
You have to look in the right place to find the essence of humans → the ensemble of social relations.

The atomised, isolated, abstract individual is a dead end which must not be our unit of social analysis. That belongs to the capitalism social form.

An individual is nothing more or less than a vehicle of dynamic social relations. Our individual self is spin, we invent ourselves from the available social relations. The idealised, independent, autonomous, successful individual in capitalist society is merely someone who has selected the social memes, and is a slave to those memes, that make for success in capitalist society. They have an individual body but a human is fully social, not just a body.

I believe that Marx's theory can be updated and that Wolff-Michael is making a valuable contribution to that. My notes on Wolff-Michael's book are here, which includes further references most of which I have yet to read or only skimmed myself.
